Dallas Area Rapid Transit (DART) is set to begin the South Oak Cliff Three Line Extension project on 24 January at its headquarters.
Expected to open in late 2016, the Blue Line extends north from Ledbetter Station through downtown Dallas, Mockingbird Station, Northeast Dallas, Garland and Rowlett.
The transit agency said that work on the 2.6-mile extension of its Blue Line light rail transit system from Ledbetter Station to the UNT Dallas campus is underway.
New stations will be added at Camp Wisdom and UNT Dallas, while Ledbetter Station, which currently the southern terminus of the line, will be redesigned to improve the flow of bus and pedestrian traffic.
The extension will provide potential development opportunities in the area south of Ledbetter Station to the UNT-Dallas Campus.
Camp Wisdom Station will be located near a future City of Dallas recreation center, while UNT Dallas Station will be located adjacent to the campus.
Dallas Mayor Pro Tem Atkins said: "This extension has great potential development opportunities for the area south of Ledbetter Station and on to the UNT-Dallas Campus."
DART said that the extension to UNT Dallas will complete the current light rail expansion and take the length of the US longest light rail system to 93 miles.
DART opened the first section of the Blue Line, from downtown Dallas to Illinois Station, in June 1996 as part of its initial 11-mile of light rail. The second section of the line from Illinois to Ledbetter was opened in May 1997.
Northern extensions from downtown Dallas to Mockingbird was opened in January 1997 and from Mockingbird to Garland in stages in 2001 and 2002. The line from Garland to Rowlett was completed in December 2012.
